Evolutionary benefit?
[edit]Both males and females of the African jumping spider species can cannibalise their partner after copulation. "That equal opportunity behaviour extends to two-way cannibalism as well, with males consuming their loved ones only slightly more often as the reverse" (full article)
My question is - what evolutionary benefit does the male get by eating the female with whom he has just mated? Isn't he reducing his chances of passing on his genes?

- Not every action of every animal serves an evolutionary purpose. But if his options are between starving to death or eating his mate and having to wait for the next female, eating the first mate is certainly more likely to allow him to pass on his genes. 65.131.48.150 (talk) 19:50, 28 August 2022 (UTC)
